ICD-10 Code B67.99 – Other echinococcosis (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code B67.99 – Other echinococcosis
What it is
B67.99 identifies echinococcosis caused by Echinococcus infection when the site or form is not otherwise specified. Use it for documented hydatid disease that does not fit a more specific code.
Clinical signs
Clinical features vary; refer to documentation. Echinococcosis may present with a cystic mass, abdominal discomfort, or incidental imaging findings, depending on the organ involved.
When to use this code
Use B67.99 when the provider documents echinococcosis, hydatid disease, or Echinococcus infection without naming a specific site or subtype. It also fits cases where the record confirms echinococcosis but does not provide enough detail for a more specific code.
If the note identifies liver, lung, or another organ-specific involvement, check for a more precise code first. When documentation is incomplete, code only what is clearly supported.
Do not use for
Do not use this code for suspected infection, exposure only, or non-Echinococcus parasitic disease. If the record specifies a different echinococcosis type or site, choose the more exact code.
Coding tip
Look for the organism and anatomic site in imaging, pathology, or provider notes before defaulting to B67.99.
